Depends on what you're doing. If you want to write systems code, Swift is very allocation-happy and will probably not be the best fit. They're trying to make an embedded Swift, but progress is pretty slow, since that's not going to be something that gets anyone promoted.
If you just want to write A Thing, then it's up to your individual taste, what's available in the ecosystem, etc.
Apple has started using Swift for production embedded code run within the Secure Enclave. I've been looking out for any evidence whether they are using it in the C1 modem baseband.
I don't think I'd push for it over Rust for those applications, but there is apparently wood behind the arrow internally.
